This is the further research based on the topic that we chose. I finally decided to focus on the air pollution. The reason for that is because this is the mean enviornmental problem in China now and it has threat lots of people’s health and it get more and more seriously in the recent years. So those reason I did the further research on this air pollution problem. The research is basically about the history background, effect, cause and unknown facts about this air pollution pollution. I also did some research about the existing solution for the air pollution that create by others.
